We had the factory TrailAir pin box installed when we first installed the AirSafe Omni Direction hitch. It was OK on generally smooth road but when we hit bumps or dips at freeway speed, there was too much movement between the truck and the front of the trailer and it felt out of control. IMO, a single air system is enough.
